Cartographic survey is an important way to preserve our heritage. It records
the architectural structures and features of buildings precisely and acts as
a reference for future restoration projects. The measured drawings of historic
buildings themselves are also important heritage resources, reflecting the evolvement
of Hong Kong's history and culture. Many of these age-old drawings are valuable
historical documents.

The measured drawings displayed in the exhibition were
produced by the Guangdong Provincial Institute of Cultural Relics and Archaeology,
The University of Hong Kong, The Chinese University of Hong Kong, The Hong Kong
Polytechnic University, the Architectural Services Department and the Antiquities
and Monuments Office. We hope that through this exhibition, the public can further
understand the work of cartographic survey of historic buildings in Hong Kong,
and the importance of the work of heritage preservation.
